Combining with an extracellular or intracellular peptide to initiate a change in cell activity. A receptor that binds an extracellular ligand and transmits the signal to a heterotrimeric G-protein complex. These receptors are characteristically seven-transmembrane receptors and are made up of hetero- or homodimers. Combining with an extracellular or intracellular peptide to initiate a G-protein mediated change in cell activity. A G-protein is a signal transduction molecule that alternates between an inactive GDP-bound and an active GTP-bound state. null null Combining with an opioid, any narcotic derived from or resembling opium, to initiate a change in cell activity. null null
